IMPROVEMENT IN SU LKY-PLOWS.

Specilication forming part of Letters Patent No. 2ll,007, dated December1T, 1878; application tiled J une 10, 1878.

To all 'whom it may concern:

Beit known that I, Geenen W. Gann-Nun, ef Long Point, in the county ofLivingston and State of Illinois, have invented certain new and usefulImprovements in Sulky-Plows; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in sully-plows; and it consistsin the arrangement and combination of parts, whereby the wheel may beraised or lowered upon either side and the plow readily controlled, aswill be more fully described hereinafter.

The accompanying drawings represent my invention.

Figure l is a side elevation of my invention. Fignf is a rear view oi'the same.

a represents the axle, which is made U- shaped at or near its center, soas to form a guide for the plow-beam b, and to allow the beam a verticalmovement, so that it can be raised from and lowered down into the earth.Upon each side of the bend in the axle is secured ahorizoutal bar, c,which projects forward a suitable distance, and between the l front endsof the two is rigidly secured the tongue d.

In the rear of the hind end of the tongue a pivoting-bolt, c, is passedthrough the two bars o and the front end of the plow-beam L, the saidbeam having a series ot' holes through it, so that the end can beadjusted up or down, and thus cause the furrow to be shallow or deep.

Secured upon the top oi the right-hand bar c, and to theside of thebentportion of the axle, is the curved rack f, in which the spring-catchr/ snaps, the catch being secured to the lever h. To the lever isfastened the elevatingchain j, which passes back over the top of theroller fe', which is pivoted in the upper end of the space formed by thebend of the axle, and is fastened to the top of the plow.

By moving the lever h back and forth, the plow can be raised above andlowered down to the earth.

It will be noticed that the space between the bent portions of the axleis just wide enough to allow the beam to move freely up and down, butwill not allow it the slightest lateral play.

Secured one upon the top of each end of the axle are the right-angularstandards or supports Z, which have their upper ends made circular, andprovided with a number of recesses, o. Pivoted to the outer sides ofthese standards are the levers n, which are formed in a single piecewith the axles upon which the driydng-wheels p are placed.

By moving the levers a (which are provided with suitable catches Q.)back and forth, the driving-wheels may be depressed, so as to cause theaxle to be raised upward and the plow to cut but a shallow furrow; orthe wheels may be raised upward and the plow made to cut a deep furrow.

As the two levers are adjustable independently of each other, one wheelmay be depressed and the other raised, so as to cause one side of themachine to run higher than the other, as when one wheel has to run inthe furrow. Y

Each of the levers n is provided with a catch, Q, to catch in therecesses or notches o, and thus hold the wheels in any desired position.

Fastened to the top of the bent portion ot' the axle is the support n,to which the seat a is secured. Thus it will be seen that the bentportion of the axle serves as a support for the seat, a guide for theplow-beam, and to receive the roller over which the chain passes.

I am aware that axles have heretofore been made with bends in them thatact, in conjunction with other parts, as guides for the verticalmovements of the plow-beams, and thls 1 disclaim.

My invention consists in forming the bend' as a guide for the plow-beam,and to receive of such a shape that the roller can be ysethe roller overwhich the elevating-chain cured in its upper end by means of a singlepasses, substantially as shown.
